Abstract
Air distillation installation comprising: (A) an air compressor group (1) whose output is connected to an outlet coupling (11); (B) two cylinders (2A, 2B) for the purification of air by adsorption having inlet/outlet couplings (12A, 12B); (C) a first framework (13) in which are mounted: (a) the accessories downstream of the compressor such as an assembly (14, 17) for precooling air; (b) accessories of the purification cylinders, such as an assembly of valves and a regeneration gas reheater (18); and (c) the connection conduits of the mentioned accessories, with their safety members and their automatic and/or remotely controlled valves, these conduits terminating in couplings (15, 22A, 22B, 23) for connection to other portions (1, 2A, 2B, 4) of the installation, and the corresponding monitoring, control and instrumentation members (21); (D) a second framework (31) in which are mounted: (d) the principal heat exchangers (24) and the subcoolers (25); (e) the assembly of the cold accessories such as the cryogenic valves and the cryogenic pumps (26) and the expansion turbines (27); and (f) the conduits for connecting the elements mounted in the second framework, with their safety members and their automatic and/or remotely controlled valves, these conduits terminating in couplings (29, 30) for connection to other portions (3, 5) of the installation; (E) an air distillation column (5) provided with a certain number of couplings (33) for the inlet and outlet of fluids; and (F) tubes (6) for connection between the associated couplings (11-15, 12A-22A, 12B-22B, 23-29, 30-33) of the portions (A) to (E) of the installation.
